Abstract

The invention discloses an antiskid and abrasion resistant tire rubber composition. The antiskid and abrasion resistant tire rubber composition comprises the following components in parts by weight: 25-45 parts of butadiene rubber, 20-30 parts of natural rubber, 10-20 parts of ethylene-propylene-diene monomer rubber, 10-20 parts of high dispersive white carbon black, 20-30 parts of carbon black N330, 30-50 parts of carbon black N220, 1-5 parts of nano-zinc oxide, 2-4 parts of tackifying resin, 0.5-2 parts of anti-aging agent SP, 1-2 parts of anti-aging agent 4010 NA, 1-2 parts of anti-aging agent BLE, 3-8 parts of vulcanizing agent, 2-5 parts of sulfur, 0.5-2 parts of accelerant TBZTD-70, 1-2 parts of accelerant CZ, 2-4 parts of plasticizer DPDP, 3-6 parts of coupling reagent and 2-5 parts of aromatic oil. The antiskid and abrasion resistant tire rubber composition provided by the invention is excellent in wet grip, high in wet land driving safety factor, good in anti-abrasion performance and high in tire comprehensive using performance.

Description

technical field [0001] The invention relates to the field of rubber products, in particular to an anti-slip and wear-resistant tire rubber composition. Background technique [0002] With the development of automobiles in the direction of high speed, safety, energy saving, and comfort, the requirements for high performance tires are also increasing year by year, which puts forward higher requirements for tires' wet skid resistance and wear resistance. [0003] The existing ordinary tires are poor in wet skid resistance, and the road surface is easy to slip in rainy days, causing serious safety hazards. Improve its wear resistance while improving its anti-skid performance. Contents of the invention [0004] The object of the present invention is to provide a rubber composition for anti-slip and wear-resistant tires, which has better wet grip and dry grip and better wear resistance. [0005] In order to achieve the above object, the technical solution provided by the presen...
